FIELD: physics, radio.SUBSTANCE: invention relates to radio communication and is intended for use in radio devices for television, radio broadcast and radio communication in the HF and VHF ranges. Disclosed is an integrated multidipole antenna consisting of dipole arms, each formed by multiple wires arranged along the surface of a cylinder and converging to the edges of the arm to one point, wherein all arms have different sizes, and each smaller arm is completely placed inside a larger arm. Arms of the same length can be merged into symmetric dipoles, wherein a symmetric dipole of a smaller size is placed inside a similar dipole of a larger size. Symmetric dipoles of a smaller size can be completely placed inside the arm of a symmetric dipole of a larger size, and wires of the larger dipole can be placed primarily at one side of the cylinder forming the dipole.EFFECT: repeated usage of space occupied by an antenna, ensuring operation thereof in multiple spaced-apart frequency ranges, and improved directivity of the antenna at multiple frequencies.6 cl, 1 tbl |
